Be it known that I, RAYMOND S. DnvNnY,

Va citizeniofthe United States,`residi ng at by reason of certainspeed-increasing vgearing, serves to actuate the agitating means withinthe churn body at increased speed, and at the same time winds up otherparts for the immediate application of the weight again, upon thecompletion of a full downward vvpassage of the same, so that theoperation of thek motor is practically acontinuous one.

.A further object to provide aimachine l havin@ the abovecharacteristics which ma be readily changed for operation by vhand or tobe operated automatically, and wherein a prime desideratuin has been toconstruct the, several parts as economically as. possible in .order torender the same capable of being manufactured at a low cost..

- A. full yand complete Vunderstanding of the invention may beobtainedfrom a considera;l tion of the following detailed description,

Y taken inconnection withthe'accompanyingY drawing forming a part-ofthis specification; it beingunderstoodthatl while the drawing Shows apractical form of the invention, the latter is'not confined to strictconformity therewith, but maybe changed or modified, so long as suchchanges. or modications mark no material departure from the salientfeatures of thev invention, as specifically pointed outin the appendedclaims. v

In the drawing, in vwhich similar reference characters designatecorrespending parts througlioutthe several figures Figure 1 is a, frontelevationV ofl the improved motor for churns,l some of the parts beingshowny in section. .V-Fig. 2 vis a horizontal sectional view,v taken onthe line 2,-2'of Fig. 1,-.and Fi-g, V3, is a side elevation vof thelower'portion of the'V machine. i

The major, portion of the herein described machine,in accordance withthe stated object to constructthe same with rigid adherence to economy,is formedof wood of the proper kind, it being foundl that thelatter-material has the advantage of combining the necessary strengthyandv lightnessjand lending itself admirably to structures of thischaracter. 4 'i YA .supporting framework provided comprising a pairofspaced uprights 1 1, which are appro riately connected'to base sills2%2,'adaptec to rest upon the floor or other support, and thesaid,uprights are furthersupported in upstanding position by inclined braces3 3, arranged in pairs Y and connected to eachv upright, as-by pins 4 4,and adapted to rest upon said iioorin front and in rear ofthe same,andthus preventing any tilting movemen't ofthe uprights, as clearly shownin Figz vof the f drawing.

, The uprights l:-1are connected, adjacent i to theirtop ends,pby avcrossubeam 5-which,

like the uprights, the base sills andthebraces, may be formed of woodand @is suitably secured to said uprights bymetallic brackets y 6-6bolted or otherwise fastened tothe i said b e'am and uprights 'lhe cross beam 5 is provided ata central point with a groove lor slotZieXtendingfroni line of thesame,for a purpose to be ex-` one edgethereof to the longitudinal center plained, and is 'furthermore adaptedto support a pair of brackets 8 and 9 respectively, in the form ofcastings, arranged in spaced relation to the said slot and suitablysecured f' .to the beam as by screws for bolts. bracket 8 comprises abaseportion for at-y tachment to the beam and has 'ani overhangingprntiony 10 adapted to overlie the slot 7 and provided witha socket 11`in its lower facev in'alinement with the said slot; The

The i' said bracket 8 'also has an upstanding 'arm .12 located overthesocket 'and provided with a transverselydisposed bearing opening 13',which is `in horizontal alineinent" with a similar bearing opening 14provided at the upper end ofthe other bracket 910e cated at the oppositeside of the slot'7 1 rllhat upright or standard 1 located nearer to thebracket 9 vis provided with abearing opening 15 Vabove thebearn, iand inaline: A

vinent- `with the aforesaid.bearings"13y and 14, and through theseyseveral .bearingsis adapted'to be passed a horizontal shaft 16 whichVconstitutes a: power. shaftr 'when the i y v Y device isarranged to bedriven by hand, as

through the medium of a hand crank 17, indicated kin dotted lines inFig. 1 of the drawing.'

A crown gear wheel 18 is vsuitably secured' to theshaft 16 between thebrackets'8 and 9, the teeth ofl said wheel facing toward the slotV 7,and a pair of spools 19and20 are suitably mounted to rotate with theshaftv 16 and arranged adjacent to the bracket 9 for the purpose ofvconnection with the weight-driven mechanism toibe later described.

-A rectangular churn-body 21 of any desired capacity and l.formed of.vsheet metal, wood or Crockery-ware -is located/beneath thebeam 5, .thecenter of the same being normally in vertical alinem'ent with the socket11 andthe Vslot 7. The churn-'body 2f1-is adapted to be supported by 'apedestal 22, V,suitably ysecured thereto andl resting upon a base23supported by the lioor. `Thev base 23 carries an upstanding pin 24entering a suitable seat formed in the lower end of the pedestal 22and.serves'toprevent any lateral movement 'of the churn-body and lpedestal 'relative tothe said base; AThe base f and pedestal maybeformed ofiwoodand are preferably provided with suitable antifrictionmeans, such as ball-bearings 25 to support the weight'of thechurn bodyand its contents andfreduce the friction of the Y bearing vto a minimum.

VvThe churn-body 21 is provided with a suitable'lid '26, hinged asv at27'to the rear edge of said Vbody andv having. suitable clamps 28 forholding the same in position during the revolving motion of thebody,.and also-provided with a-sight opening v29 for the purposes ofobserving the progress of the churning operation.

Y A metallic tubular post 30, having an enlarged base portion 31suitably secured to the center of the lid is adapted'to extend gear 18.Y

upwardlyand through the slot 7 formed in the cross beam 15,' and isprovided at'its upper end with. a horizontally disposed gear wheel 32preferably'formed integral therewith and normally lying vin meshingrela'- tion with the lower portion of the crown the tubular sleeve 30from its position in the slot 7, a locking member 35, formed ofsuitablespring wire is secured to the beam y 5, vas at `36, at one sideofthe said slot-7 and extends across the latter and is adapted toVengage behind an upstanding4 pin 37v located on the upper face of thebeam 5 and 'thus surround the tubular sleeve 30 and confine the latterwithin said slot-7.

The shaft 33 carries at its lower end a dasher-hub 38 provided witha'pluralityiof paddles 39y having the perforations V40 Vfor permittingthe passage ofthe milk within the churn-body 21,*the said Vhubl38 `beingdetachably connected 'to the shaft v33 by a set-screw 41. 1 f* Theconstruction and operation vof. the .Y hand-driving means will beVvreadily'understoodfVVhen it is desired to churn a quantity of milk,the churnbody21 is removed from the frame of the machine, and the milkis placedwithin'the body, the lid 26 lbeing thrownvback upon its vhingesfor the purpose: Then the dasher is secured upon the inneror lower endof the Vshaft 33 through the medium v of the set-screw 41:

Next the lid is closed and locked upon the churn body 21 by means oftheclamps 28,

and the dasher and shaft are allowed to drop when the dasher will yrest'upon the bottom of the churn-body, and the top ofthe said shaft 33 willproject only slightlyabove the gear wheel 32, free to Vpass beneath theoverhanging portion 10'of the bracket 8. Upon sliding the churn bodytogether'with the base 23 into position, the Vshaft 33vmay be elevatedinto position within the socket A11, yand be secured therein by theset-screw 34v and thespring lock 35 engaged around thetubular sleeve 30.In order to adapt the machine for weightdriven means, the upperv endsofthe uprights 1-1 are each provided with mortises 42, into which areadapted to 'be Vfitted corresponding portions of extensions 43 which areof sufficient heightv to provide the necessary fall for 'the purposedesigned. The

upper ends vof the extensions are Vvprovided with ball-bearing socketmembers 44-a`dapt ed to receivev the end portionsof a horif zontallydisposed shaft 45, preferably formed of a wooden bar, round forsjthemajor portion of its length and having r a squared portion 46'arrangedover ythe shaft 16, said squared portion having secured thereon, a pairof relatively largesheavesr 47 Aand 48, locatedy respectively overY thespools 19 and 2O and-,connected therewith f with reverselv wound strands49' and V50 respectively. ach of the strands 49and 50', which may be ofsome suitable, strong, flexible cord or rope,- are substantiallysequalin length to the heightl of Vthe shaft 45 Vabove i the floor or support,`'and while themajor portion of one strand 'is wound upon the propersheave in onedirection, thel major portion of the other strand is woundupon its proper spool in the "other'direction', so

that when a revolving Vmotion is imparted to the top shaft 45, in amanner to be described, it will readily be seen that one of the strands49 or 50 will tend to rotate the shaft 16 in the same direction, whileVthe other strand will be wound up upon either its sheave or spool, andin the opposite direction ready for the next operation of the device. Y

In order to impart rotary motion to th shaft 45, a pair of relativelysmall spools 51r and 52 are mounted upon the squared portion 46 thereof,near the adjacent extension 43 and have reversely wound thereon strandslocated at the top of the machine, that the oothe churn.

shaft v45 will be rotated in a direction ,depending upon the directionof winding of said strand, and that the shaft 16 will be correspondinglyrotatedby means of either the strand 49 or 50, and. that the reverse ofthe operation is obtained by every alternate engagement of the weight 56with the strands 53 and 54, so that practically a con# tinuous operationof the machine may be obtained by merely changing the said weight Byreason of the rectangular formation of the churn-body, the entirecontents of the same is thrown against the stationary paddles 39, theperforations 40 formed in the same permitting the passage of some of themilk and resulting in the rapid breaking up ofthe fat cells therein, andthe quick pro-A duction of butter. Y

The following are the steps necessary to obtain access to the interiorof the churn to remove butter therefrom, and clean the dasher, etc.First, the set screw 34 is loos-Y ened, which will permit the shaft 33and its dasher to drop to the bottom of the churn. Then the latch 35 isdisconnected, where# upon the sleeve 30 with .its gear may be movedoutwardly -through the slot 7 and the churn itself with its base may bemoved out of the way of the framework. Then the llatch `means 28 may bedisconnected. The shaft -33 should now be pulled upwardly to bring thedasher 39 up against the under side of the lid 26. The lid may now beswung open without interference of the dasher withthe4 sides of thechurn, by taking advanta e of the rectangular shape of ith the lid onceswung open, it is easyy to disconnect the set screw 41,

whereupon thefdasher may be removed from its shaft and the contents ofthe churn itself e may be removed.

.Obviously, my improved motor mechamsm maybe used to drive or rotateother things than churns, and while a churn has been described in somedetail in connection A with the invention, I do not wish my invention tobeV considered as being limited to such use.

Whatis claimed is:-

1. The combination with spaced uprights, an intermediate cross beamconnect-lng the,

uprights, a body mounted for revolution between the .-uprights andhaving a-closure, a spur, ge-ar carried by the closure and having abearing in the cross beam, spaced brackets carried by the latter andhaving horizontally alined bearings, a counter shaft mount-A ed in saidbearings and adapted to receive a hand crank and carrying a vcrown gearin normal meshing relation with the spur gear,

a stationary shaft secured against rotation Y in one of the bracketsandextending into' the body7 a .pair of spools mounted onthe icountershaft, a shaft mounted fat the top of the uprights and havinga'pair of sheaves in alinement with the saidl spools, strands reverselywound upon the sheaves and connected with theV spools on thecountershaft,

a second pair of spoolsmounted on the topf shaft and having reverselywound strands arranged thereon, and a weight for alternate kconnectionto the last named strands for actuating the machine.

2. The combination` with a gear-supporti ing frame-work including spacedupright i standards carrying gearing including a pair Y of spools and agear, a body mounted for rotation between the standards, a shaftextending within the body and secured against rotation to theframe-work, a gear carried i by the lid of. the body and adapted to beplaced in vmeshing lrelation with theg'irstnamed gear, a shaft mountedatthe top ofthe standards and having sheaves, strands reversely wound uponthe same, and alternately extended and connected to the spools, a secondpairof spools carried bythe shaft and having strands secured thereto foralternate reverse windingv thereon, and a weight for alternateyconnection to thelast-named strands. e i

In testimony that I claim the foregoing as my own, I have* heretoaffixed my signature e in the presence of two witnesses.v
